Help! Vaginal bleeding (?)

I tried losing my virginity like 3 weeks ago and it hurt a lot and I bled and it just didn't really work. Up until then I was able to use sex toys, even sort of larger ones. Now whenever I try I bleed (without major pain) even though I never used to. Today I've noticed I'm having slightly brown/stringy discharge but I dunno if that's period related or not. There's also a sort of strong smell. It's not a rancid smell or anything, it's just strong. I did also get in a pretty bad bike accident 2 days ago (had to go to the er) so I dunno if that somehow affected it or if its related to my cycle or what. Anyone know what could be going on or if its related to how long ago I tried to have sex?
